What is the relation of the perception, memory and learning to the cognitive ang moral development?

Every word of your question is the subject of many books. The words are only vaguely related to each other.

When two or more people live in the same area they have to adopt some rules about who does what to whom. Any such rule is called a more', French accented e pronounced "mor-ay". The adjective form is moral, and the habit of following more's is morality. More's are arbitrary: they do not have to be right, only accepted. Another group on the other side of the river might have very different more's.
